America’s 250th anniversary falls in 2026, marking 250 years since the Declaration of Independence was adopted.
The Continental Congress adopted the Declaration on July 4, 1776. Counting forward 250 years places the semiquincentennial in 2026, with July 4 serving as the central anniversary date.
The term “America250” is commonly used for the nationwide commemoration. “Semiquincentennial” is another name for a 250th anniversary, although it is much less familiar in everyday speech.
The anniversary commemorates American independence rather than the adoption of the Constitution, which occurred in 1787, or the first presidential inauguration, held in 1789.
